For example, it is advantageous to take location information of the recording location into account in the evaluation (e.g. using GPS), as this is associated with the location probabilities of the object to be detected. It is also conceivable to measure the distance to the object in addition to taking the image. This can be done using a separate or integrated rangefinder. The actual size of the object can be determined from the distance to the object and the subjective object size (e.g. number of pixels in the image). The object size determined in this way or information about the date/time of the recording or the current weather situation can also be taken into account as further parameters in the detection.
